Probing Left-handed Heavy Neutral Leptons in the Vector Scotogenic Model

Abstract

In this work, we consider an extension to the Standard Model composed by a Massive Vector Doublet under SU(2)${}_L$ and a Left-handed Heavy Neutral Lepton. We study the production of these exotic leptons with the Same Flavor Opposite Sign standard lepton pair, and jets, considering Drell-Yan and Vector Boson Fusion as independent cases. We find that for the latter, the dilepton angular distribution is different enough from the background to use it as a smoking-gun for our model. Based on this fact, we establish limits on the parameter space considering previous experimental searches in this final state.
